Many people discover that as they age, they're more willing to spend less on their lifestyle. Indeed, with the likely exceptions of healthcare or assisted-living costs, most people's core living expenses drop in their 70s. Thanks to grown children, paid-off mortgages, and the potential for "homestead" exemptions for seniors to lower their property taxes, many of the major expense-drivers affecting younger folks no longer apply. The costs you cut today turn into savings you can spend in the future if needed.
